Too hot... or too cold?

[Eolith]

I've got a question for all of you... would it be better to risk having my betta stay cooler than optimal... or warmer?

He's currently in a 1 gallon critter keeper without heat and it's staying at around 72 degrees. I have a hydor mini heater that I could use for him, but it's rated for a 2-5 gallon tank. Will it cook him if I put it in his 1 gallon container?

I'd probably say its better with a heater until you can get a better fish tank or heater. If it was glass then probably no as you would run the risk of the glass cracking, but Critter keepers are plastic so that shouldn't be too much of a problem.

Yeah, bettas should be in temperatures of 78-82 degrees. Just make sure to keep tabs on the temp with a thermometer because the water could get too hot in a small tank.

Those Hydor minis are only meant to raise the room temp a few degrees anyway, so i think you shoud be okay.
